Zooplankton Community Structure

The zooplankton community structure of 696 lakes in Pleistocene glaciated eastern North America indicated to us that glacial influence was the primary determinant of community structure. Using this criterion we successfully discriminated 82% of the lakes between glacial lakes, to which Diaptomus sicilis, Limnocalanus macrurus, Mysis relicta, and Senecella calanoides were restricted, and nonglacial lakes, to which Cyclops scutifer, Eubosmina longispina, Daphnia pulex, D. catawba, and other species were characteristic. A third large group of common species was distributed throughout the study area with no particular relation to glacial lake influence. No clear patterns in community structure with respect to size of zooplankters were discerned. Although some species distributions or abundances were consistent with the well-known predatory and competitive interactions among zooplankters typical of small lakes and ponds, for example, the negative correlation between the predatory Mysis relicta and Eubosmina longispina, most were not. We suggest that this arose partly because the study area is large and heterogeneous and partly because the biological interactions observed in small lakes and ponds may be less intense in the more physically complex environment of large lakes.Key words: zooplankton, community structure, glacial opportunists, multivariate analysis, zoogeography, size-efficiency hypothesis

Lake Simcoe

Fuzzy clustering generates cluster membership weights that indicate how tightly each object is linked to its cluster relative to other clusters of a dendrogram. In a fuzzy clustering of the crustacean-zooplankton taxa of Lake Simcoe, a large (720 km2) hardwater lake in Ontario, Canada, we show how the membership weights can be used to rank all taxa for their contribution to the sampling unit (SU) classification, where the total number of SUs was 84 (7 years × 12 sampling sites). The validity of the results was confirmed by comparison with other more traditional methods of identifying variables important for object classifications and by permutation tests of matrix correlation before and after removal of low-ranked and highly ranked species. Fuzzy clustering of Lake Simcoe SUs also revealed (i) the likelihood of trends in zooplankton community composition over the 7-year period and (ii) differences in composition possibly related to sampling-station depth. In particular, the shallowest sampling station in southern Cook's Bay had a zooplankton community structure that differed significantly from other stations during all years of the study. As a preliminary screening or data exploration tool, fuzzy clustering is particularly useful for analysis of ecological data.
